The pathology and surgical treatment of tumors . Fig. 83.—Adenoma of breast; X 115, reduced one-fifth (Surgical Clinic, Rush Medical College, Chicago) : a,shrinkage due to hardening; i, proliferating ducts ; c, fibrous tissue. reason to believe that during the future growth of such a tumor thestroma would increase more than the parenchyma, and so renderthe fibrous structure more apparent. Adenomata without cyst-forma-tion never attain a large size. Usually they rangein size from that of a pea to that of a walnut;99 per cent, of them occur in females. Adeno-mata occupy more frequently the superficial andperipheral than the deep and central parts ofthe gland. They are often multiple in one breast,seldom in both breasts. They often cause greatpain and are quite tender on pressure. These Astiey cooper)symptoms are much less prominent in the early history of carcinoma of the breast. Adenoma of the breast (Fig. 84)is always well encapsulated. Adhesion to the skin and retraction are.

The existence of a well-defined capsule isof great assistance to the surgeon in doubtful cases after he has exposedthe tumor to make a positive diagnosis of its non-maHgnant nature.
